A.2.5.1 Global service check timeout limit

The master Nagios configuration file, nagios.cfg, contains global settings that control overall
behavior. One of these settings is the service_check_timeout interval. Nagios limits the
execution time of plug-ins to this interval. If a plug-in is still running when the interval expires,
Nagios stops the plug-in and shows the result as a Service check timeout error.
For configurations with fewer than 256 managed systems, the default value of 180 seconds is
adequate. However, warning or critical messages can occur if the service_check_timeout
interval ends before the metrics gathering is complete. If your configuration has more than 256
managed systems, increase the value for the service_check_timeout parameter.

A.2.6 Disabling individual Nagios plug-ins

Nagios plug-ins are enabled by default. However, you can modify the /opt/hptc/nagios/
etc/templates/*_template.cfg

files to customize the service checks as needed.

IMPORTANT:

Do not modify files in the /opt/hptc/nagios/etc directory with file names of

the form *_local.cfg or xc_*.cfg.

To disable a specific Nagios plug-in, follow these steps:
1.

Log in as the root user on the CMS.

2.

Change to the following directory:

# cd /opt/hptc/nagios/etc/templates

3.

Determine the appropriate template file to disable the plug-in.
This procedure uses the nagios_template.cfg file as an example.

4.

Use a text editor to modify the template file.

5.

Restart the Nagios service:

# /etc/init.d/nagios restart
